It's now official. Here's an excerpt of the statement released yesterday:
With the 18x RPA career field not at full capacity to reach manning requirements to fulfill current demands, the Air Force is in the process of re-posturing itself for enduring RPA operations. The decision has been made by the Chief of Staff to once again continue supplying rated pilots from UPT to fulfill RPA assignments. For the next year starting with the upcoming 15-13 class, there will be 2 RPA slots per assignable graduation class at each base (Columbus, Vance, and Laughlin) for a total of 6 RPAs per assignment class. These two assignments will be primarily sourced from T-1s due to fighter cockpit manning. While T-1s are the primary source, the exact ratio of T-1s to T-38s is unknown at this time.
